In Professor Sun’s guest lecture, he discusses the usefulness of using quorum-sensing and the applications it has to determining cell density, diffusion and efficiency. 1upg is a system that is controlled by quorum-sensing, working to relocate plasmids containing tumor-inducers into the protein. By transferring these plasmids to 1upg, it allows the ‘bacteria to synchronize infection’ when the sensing cells have become involved. 1upg is comprised of a 2-chain structure, and has a cluster of 3 ligand sites within the protein. When a look is taken at the backbone structure, we see that very little of the molecule disappears, showing us that the structure is fairly simple and not complex. We also can see that the changed areas of the molecules is standard to that of normal proteins, where the charged areas are placed on the outer structure of the protein, where it can interact with water.

Theamino structure shows that 1upg is mostly comprised of 4 different amino acids.

This protein works by binding with TraR, a regulator, which in turn prevents it from binding to DNA. overall, TraR is also regulated by TarM, and the normal functions of 1upg without the addition of quorum-sensing involves regulated the transcription of DNA as well as being DNA dependent. With the addition of TraR, taking away it's ability to bind with DNA, allows us to use this as a tumor-inducing plasmids within the 1upg.
